ABSTRACT:
A brush attachment for a power tool, such as an electric drill, capable of rotating a suitable shaft including an attachment body containing a longitudinally extending chamber and an elongate shaft rotatably mounted in this body and projecting from a rear end thereof. A cam and cam follower mechanism in the chamber convert rotary motion of the shaft into a reciprocating linear motion. There is a shaft mechanism mounted in the body for sliding reciprocating movement only relative to the body and connected to the cam follower. This shaft mechanism projects from a front end of the body. A brush is attached to a front end of the shaft mechanism and reciprocates with this mechanism in the longitudinal direction thereof. The brush attachment can be mounted on the power tool so the attachment body remains stationary relative to the tool when the shaft is rotating.
